Most property projects don't fail on bricks and mortar — they fail on compliance, energy performance, and details developers underestimate.

In this episode, we sit down with Productive Energy founder Nate to demystify SAP, EPCs, ventilation, airtightness, and sound testing — and show you how to get them right first time.

What we cover:

• What SAP assessments really are — and why they matter more than most developers think
• The biggest EPC killers in refurbishments, HMOs, and conversions
• SAP Design vs SAP As-Built (and why missing documents can cost you money)
• Easy, low-cost upgrades that have the biggest EPC impact
• Ventilation mistakes that lead to mould, complaints, and failed inspections
• Airtightness tests explained simply (and how not to overdo it)
• Why sound tests fail — and proven acoustic build-ups that pass
• What's unique (and risky) about commercial-to-residential compliance
• How poor early design decisions massively increase costs later
• How to avoid retests, delays, and Building Control nightmares
• The paperwork every developer must collect during a project
• The biggest EPC myths developers still believe
